Routing number is a nine digit code assigned by the bank to its branches in different states for the purpose of identity of the location of the account while carrying out a number of online as well as offline banking processes.
Logrolling is the process by which politicians trade support for one issue or piece of legislation in exchange for another politician's support, especially by means of legislative votes (Holcombe 2006).
The log records the start of a transaction, all the changes considered to be a part of it, and then the final commit or rollback of the transaction. Each database has at least one physical transaction log and one data file that is exclusive to the database for which it was created.
